    <p>I have to do some processing on a file loaded by the user. This process can take a long time based on the number of pages within the file. I am planning on using jQuery UIs progressbar and telling the user how many pages have been processed. However, my progress check does not return until the first ajax call is complete. Both calls complete properly are connecting to the corresponding web methods.</p> <p>I researched this a little bit already, and I found <a href="https://stackoverflow.com/a/4863630/2486">this answer</a> to another question which pretty much stated that if both calls use the Session they wont process concurrently. I only use the Session in one of the calls though.</p> <p>What am I missing?</p> <p>This is the initial call that starts the processing of the file. I set the UpdateProgressBar to run a second after the processing of the file starts.</p> <pre><code>setTimeout("UpdateProgressBar();", 1000); $.ajax({ type: "POST", async: true, data: // my params go here url: // path to web method contentType: "application/json; charset=utf-8", dataType: "json", success: function (result) { // Do stuff when file is finished processing }, error: function (XMLHttpRequest, textStatus, errorThrown) { if (errorThrown != null) alert(textStatus + " : " + errorThrown); } }); </code></pre> <p>This is the UpdateProgressBar function:</p> <pre><code>function UpdateProgressBar() { $.ajax({ type: "POST", async: true, data: // my params go here url: // path to web method contentType: "application/json; charset=utf-8", dataType: "json", success: function (result) { var totalPages = parseInt($('[id$=lbl_PageCount]').text()); var pagesProcessed = result.d; var percentProcessed = pagesProcessed / totalPages; $('#div_ProgressBar').progressbar("value", percentProcessed); if (pagesProcessed &lt; totalPages) setTimeout("UpdateProgressBar();", 800); }, error: function (XMLHttpRequest, textStatus, errorThrown) { if (errorThrown != null) alert(textStatus + " : " + errorThrown); } }); </code></pre> <p><strong>Edit</strong>:</p> <p>This is the WebMethod called by UpdateProgressBar. The other WebMethod does use Session, but as you can see this one does not. They both access a dll, however, I tried testing without using the dll for the update and it did not make a difference.</p> <pre><code>[WebMethod] public static int CheckPDFProcessingProgress(// params go here) { int pagesProcessed = 1; try { OrderService _orderService = new OrderService(); pagesProcessed = _orderService.GetMailingPDFPagesProcessedProgress(PersonID); } catch (Exception ex) { // log error } return pagesProcessed; } </code></pre>

    1. CO@Jim Why did you remove the ASP.Net tag and remove it from the title? Are you positive it could not be something with .NET?

    2. COI removed it from the title beacuse it doesn't belong there - that's what tags are for. I ended up removing the tag because the question address only javascript/jQuery/AJAX. I don't think someone scrolling through ASP.NET questions is looking for this kind of question, or that they will be able to answer it for you. It just doesn't seem relevant to the issue.

    3. CO@Jim But I am using it on an ASP.Net website and it could be an issue involving ASP.Net could it not?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
